Patent JP-S5967018-A (JP)
Title: Preparation for polyester film
Inventor: UCHIUMI SHIGEO
IPC: B29C55/14
Filed: 1982-10-06
Abstract: PURPOSE:To contrive to raise productivity by increasing the ratio of stretching by such an arrangement wherein after a film which is prepared by melting and extruding polyester is stretched in one axial direction, it is further stretched by the second stage of operation at higher temperature, and next, it is stretched in the direction perpendicular to the previous direction and then fixed. CONSTITUTION:An amorphous non-stretched film is prepared by melting and extruding polyester containing less than 0.10wt% of infusible particles, and this film is stretched by the first stage in one axial direction until its double refractive index becomes 15X10<-3>-30X10<-3> and then it is heat-treated at such temperature higher than that of the first stage stretching so that its degree of crystallization becomes 2-15%, and after that it is further stretched by the second stage in the same direction as previous one until its double refractive index becomes higher than 80X10<-3>, and after that, it is stretched in the direction perpendicular to the previous direction and it is thermally fixed. Thermal fixation is normally carried out at 180-245 deg.C, and by this, stretching distortion of the film is removed and crystallization progresses. Thereby, it becomes possible to form a smooth film from polyeser which substantially doesn't contain infusible particles. Since projections of this film are composed of polyester itself, the film is excellent in wear resistibility.

Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To improve various coating film properties such as durability and coating performances such as surface properties and stability by applying a water base coating containing an organic solvent in a specified ratio in a coating atmosphere of specified temperature and relative humidity to keep the quantity of applied coating on one side within a specified range. SOLUTION: A resin such as an acrylic resin is used for a water base coating. An organic solvent compatible with water such as an alcohol, for example, a polar solvent, is used as an organic solvent. The quantity of the organic solvent in the water base coating is set up at 10-30%. When the quantity is below 10 wt.%, skinning which causes coating defects tends to be generated, and when the quantity is 30% or above, odors are apt to be generated. The water base coating is applied in an atmosphere 15-35 deg.C in temperature and 60-90% in relative humidity. When the temperature is 15 deg.C or below, the viscosity of the coating changes sharply, and when the relative humidity is 90% or above, bedewing tends to be generated on the inner wall of a coating chamber.
